Shanghai Ruiyu Biotech Co. Ltd. has 4 pending office actions in Chemistry & Materials. The matters are distributed across 4 distinct examiners and 4 distinct art units, indicating that the portfolio is not concentrated in one examination assignment.
CAI, PHUONG HAU is the busiest examiner, with 1 pending matter. Counsel should therefore track separate examiner and art-unit developments rather than treating the portfolio as a single examination stream.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
| Bucket | Cases |
|---|---|
| §103 only | 2 (50%) |
| Multi-statute (no §101) | 2 (50%) |
